If your subscription form isn't working, you've probably modified the HTML code for the subscription form.
Most likely, the problem is caused by one of the following:
- Removal of required hidden fields
- Changes to the form action path
- Broken Javascript code
The best way to find out exactly what went wrong is to get the HTML code of the Subscription form from Pinpointe, and test it to make that it's working. Compare what you've changed to the original code. Pay special attention to the hidden form variables, the form tag, and the Javascript verification code.
